## Create Evaluation

**post** `/v5/evaluations`

Create an evaluation together with its items, optionally running test criteria against them.

Accepts three request shapes: standalone (inline `data`), from an existing dataset
(`dataset_id` with optional per-item references), or with a new reusable dataset created inline
from `data`. When the evaluation includes tasks that require execution (for example an LLM judge
or custom function), an async job and a Temporal workflow are started and the evaluation is
returned immediately with status `running`; task results and `error_count` populate
asynchronously. When it includes only contributor tasks, taxonomy-only input, or no tasks, no
workflow runs and it is returned with status `completed`. Optional `tasks`, `metadata`, `tags`,
and `taxonomy_params` are persisted alongside the evaluation and its items.

            The ID of the Agentex agent to use

          - `input_column: string or map[unknown] or array of unknown`

            The dataset column to use as input for the agent

            - `string`

            - `map[unknown]`

            - `array of unknown`

          - `agent_task_params: optional map[unknown] or ItemLocator`

            Extra params merged into the Agentex `task/create` call's `params` object and forwarded verbatim to the agent. Required by agents that demand configuration at task creation -- the golden agent, for example, rejects any task whose params omit `config_id`. SGP always pins `is_eval: true`; a caller-supplied `description` overrides the SGP default. Nested `item.`-prefixed strings and `{{item.x}}` templates are resolved per evaluation item, so a per-row `config_id` can come from a dataset column.

            - `map[unknown]`

            - `ItemLocator = string`

          - `completion_mode: optional "first_message" or "turn_quiescence"`

            How the agent's first turn is judged finished. `first_message` (the default) grades the first non-empty agent text message after the input, which is cheap but grades a streaming harness on whatever text block streamed first. `turn_quiescence` keeps listening while the agent is still producing messages and grades once at least one agent text message exists and nothing new has arrived for `quiescence_seconds` -- the right choice for tool-using agents. Neither mode requires the agent to mark the task complete; a terminal task status always ends the wait, and `timeout_seconds` always bounds it.

            - `"first_message"`

            - `"turn_quiescence"`

          - `deployment_id: optional string`

            Optional Agentex deployment ID to pin the eval to a specific deployment. When set, RPC traffic routes through /agents/{agent_id}/deployments/{deployment_id}/rpc. When unset, traffic uses the agent's default RPC endpoint, which resolves through the agent's current routing rules on the Agentex side.

          - `include_traces: optional boolean or ItemLocator`

            Whether to include trace data in the evaluation results. Traces are read from SGP's own span store for the agent's trace, not from Agentex.

            - `boolean`

            - `ItemLocator = string`

          - `input_mode: optional "text" or "data"`

            How the resolved `input_column` is delivered to the agent. `text` (the default) sends a TextContent message with the value stringified. `data` sends a DataContent message whose `data` is the value as a JSON object; the resolved value must be an object, or a string that parses to one. Most agents accept text only and reject `data`.

            - `"text"`

            - `"data"`

          - `quiescence_seconds: optional number or ItemLocator`

            Seconds of no new messages before `completion_mode: turn_quiescence` considers the turn finished. Ignored in `first_message` mode. Should exceed the agent's longest expected gap between messages (a slow tool call), or the turn is graded early.

            - `number`

            - `ItemLocator = string`

          - `timeout_seconds: optional number or ItemLocator`

            Maximum seconds to wait for the agent's first-turn response per item. If not set, the server-side default of 600s applies. Capped at 1500s to stay within the evaluation item activity's 1800s start-to-close budget.

            - `number`

            - `ItemLocator = string`

        - `alias: optional string`

          Alias to title the results column. Defaults to the `agentex_output`

      - `configuration: object { agentex_agent_id, input_column, agent_task_params, 6 more }`

        - `agentex_agent_id: string`

          The ID of the Agentex agent to use

        - `input_column: string or map[unknown] or array of unknown`

          The dataset column to use as input for the agent

          - `string`

          - `map[unknown]`

          - `array of unknown`

        - `agent_task_params: optional map[unknown] or ItemLocator`

          Extra params merged into the Agentex `task/create` call's `params` object and forwarded verbatim to the agent. Required by agents that demand configuration at task creation -- the golden agent, for example, rejects any task whose params omit `config_id`. SGP always pins `is_eval: true`; a caller-supplied `description` overrides the SGP default. Nested `item.`-prefixed strings and `{{item.x}}` templates are resolved per evaluation item, so a per-row `config_id` can come from a dataset column.

          - `map[unknown]`

          - `ItemLocator = string`

        - `completion_mode: optional "first_message" or "turn_quiescence"`

          How the agent's first turn is judged finished. `first_message` (the default) grades the first non-empty agent text message after the input, which is cheap but grades a streaming harness on whatever text block streamed first. `turn_quiescence` keeps listening while the agent is still producing messages and grades once at least one agent text message exists and nothing new has arrived for `quiescence_seconds` -- the right choice for tool-using agents. Neither mode requires the agent to mark the task complete; a terminal task status always ends the wait, and `timeout_seconds` always bounds it.

          - `"first_message"`

          - `"turn_quiescence"`

        - `deployment_id: optional string`

          Optional Agentex deployment ID to pin the eval to a specific deployment. When set, RPC traffic routes through /agents/{agent_id}/deployments/{deployment_id}/rpc. When unset, traffic uses the agent's default RPC endpoint, which resolves through the agent's current routing rules on the Agentex side.

        - `include_traces: optional boolean or ItemLocator`

          Whether to include trace data in the evaluation results. Traces are read from SGP's own span store for the agent's trace, not from Agentex.

          - `boolean`

          - `ItemLocator = string`

        - `input_mode: optional "text" or "data"`

          How the resolved `input_column` is delivered to the agent. `text` (the default) sends a TextContent message with the value stringified. `data` sends a DataContent message whose `data` is the value as a JSON object; the resolved value must be an object, or a string that parses to one. Most agents accept text only and reject `data`.

          - `"text"`

          - `"data"`

        - `quiescence_seconds: optional number or ItemLocator`

          Seconds of no new messages before `completion_mode: turn_quiescence` considers the turn finished. Ignored in `first_message` mode. Should exceed the agent's longest expected gap between messages (a slow tool call), or the turn is graded early.

          - `number`

          - `ItemLocator = string`

        - `timeout_seconds: optional number or ItemLocator`

          Maximum seconds to wait for the agent's first-turn response per item. If not set, the server-side default of 600s applies. Capped at 1500s to stay within the evaluation item activity's 1800s start-to-close budget.

          - `number`

          - `ItemLocator = string`

      - `alias: optional string`
